Directions to Get DLG Files into ArcView

1. 1. Download the appropriate DLG files from the USGS web site.Note: see the "Quad Help" link on the GIS lab page for assistance in finding 1:100K map names. Remember that the 1:100K DLG maps come in two halves, and east and a west. The east half is divided into quadrants 3,4,7, and 8. The west half is divided into quadrants 1,2,5, and 6.
2. 2. Unzip the files.
3. 3. Rename the unzipped files with the extension *.dlg. It is a good idea to follow the DOS 8.3 convention.
4. 4. Copy the utility DLGLX149 into the directory with your DLG files.
5. 5. Run the DLGLX149 utility. A DOS window will open. From the prompt, type in the following:
   
   
   /h=12/no=lines /type=o
   
   
   Then follow the directions. If for "Input file spec", you type "*.dlg", it will merge all existing DLG files in the directory.

It is a good idea to keep each of the types of data separate: roads, railroads, boundaries, hydrography and hypsography (if it is present, it usually is not).
